My presence isn't simply about "character" - I'm present in every part and particle of the thing, in the sound and rhythm of the sentences, in the shifting tones and the selection of details, in the comedy, the sadness, and the confusion. For the space of an essay, I'm the air you breathe, everywhere and nowhere. With a personal essay, I don't think you'd want it any other way. You ought to have the sense of an encounter, the impression of having met someone. In my essays, for better or worse, that someone is me.

I suppose I like certainty as much as anyone else, but I also feel that the hidden costs are high, that we pay a heavy price for our convictions. This is a human issue as well as a writing issue - at least in the personal essay as I practice it. Any real essayist knows that certainty is an editorial decision, arrived at not through conviction but through suppression, the denial of a whole range of possibilities, of alternatives that we jettison, sometimes necessarily, in order to steady the ship.

I'm not a very savvy operator - it's not who I am, it's not what I do - and so I have to go at things in ways that suit me. I just write what I write and the stuff finds its vagrant way in the world, somehow. The venues appear; the work always finds a home, eventually.

My instinct tells me "purpose" is maybe the enemy of a good personal essay. In my own experience, I'm always lost and wandering and searching - where am I? how'd I get in this mess? what's the point? - right through to the final draft, and sometimes even beyond that - baffled and defeated still, confused as to purpose long after the thing's in print. I never really have a guiding purpose or a point, not at the outset, anyway. It's like life: It's all discovered en route.

Nowadays I imagine people find freer and more accepting venues in blogs, on Tumblr and Instagram and Facebook, in the riot of shouting that trails in the wake of every news story. So there's always the pandemonium of the Internet, if you need to get your lunatic opinions out in public. I find most of that stuff a little insane-making and my preference is to encounter personal essays in the relatively sedate and stable universe of print, in literary quarterlies, magazines and books. But I'm sure you can find plenty of good stuff in lonely outposts all across the World Wide Web.

Where exactly do you put your hands on somebody who hurts everywhere?

What the nostalgic past and the imaginary future seem to share in common is a form of idealism, perhaps a dream of wholeness. Our future is just as goopy with sentiment as our past. To me, they're the same, both very tempting, and I don't believe in either, although the idealism is probably important.
